Divided and this application filed November 11, 1927. SerialNo. 232,689.

This invention relates to machines for making insulating coverings forelectrical conductors or the like. More especially, this inventionrelates to an improved mechanism for controlling machines of the typeshown and described in Patent No. 1,789,882, issued Jan. 20, 1931, ofwhich this application is a division. Such machines are adapted to forman insulating covering in such a manner that the same will besubstantially a onepiece structure, regardless of the length of thewire, and that the covering will be of substantially uniform thicknessabout the conductor.

The insulating machines generally in use prior to this invention,covered a conductor with insulating material of various kinds bywinding, braiding, and other similar opera tions. These operations weregenerally time consuming. inasmuch as in many instances more than onelayer of material was required to properly insulate the conductor, andeach layer required a separate machine to apply the same. The design ofthe machines used,

was such that only a limited length of con-- ductor could be covered atone adjustment thereof, after wh ch the conductor was severed, themachine readpisted and the conductor ends rejoined. Insulating coveringsmade by previous machlneswherem the strands of the covering werehelically wound upon the conductor, had the disadvantage of a tendencyfor the strands to separate when the covered conductor was sharply bent,which destroyed the insulating qualities thereof.

One object of this invention is to provide an improved machine for usein covering a conductor or the like, with'an insulating material whichpreferably comprises a loose,untwisted roving or rovings of threadreinforced fibres, and wherein these rovings are wound upon theconductor in a novel manner, and then bound together with a bindingcompound, compressed, and smoothed into a dense mass of intermingledfibres, thereby forming a substantially one-piece structure.

Another object of this invention is to pro:

vide in a machine for winding strands of-in sulating material upon thecore member, im-

proved stop mechanism for arresting the action of the machine, which isautomatically operated by an interruption in the strand of insulatingmaterial.

Still another object of this invention is to provide in a machinewherein a plurality of cheeses or the like of roving are rotated about aconductor or core member to wind the roving thereupon, improved meansunder the control of the rovings to interrupt the rotation of thecheeses about the core member.

Still another object of this invention is to provide an improvedautomatic stop mechanism for a machine of the'character mentioned, whichis simple and efficient.

A further object of this invention is to provide an improved stopmechanism for an insulated wire making machine which may be readilyadjusted to suit the requirements of the product of such a machine.

A still further object of this invention is to provide an improved stopmechanism for an insulated wire making machine wherein a plurality ofcops of insulating material in strand form is used, which willefiiciently operate under control of the strand material to stop themachine and which is adapted to be readily set in an inoperativeposition and automatically placed in an operative posi tion to suit therequirements of the product of the machine.

To these and other ends, the invention consists in the novelfeatures andcombinations of parts to be hereinafter described and claimed.

The machine selected to illustrate the features of this invention, isadapted to apply a layer of insulating material having the cation abovereferred to, have been omitted,

as the'same were not specifically pertinent to this invention. Forinstance, only one machine section which includes a rotary winding head,a compound applicator, and a compressing and polishing device, with thedriving mechanisms therefor where required, is illustrated, togetherwith a power driven conductor feeding means and a conductorstraightening device.

Aocordin to the methods described in the above noted applications, aconductor 10 is fed to the machine passing first through a straighteningdevice wherein kinks, bends, etc., are taken out of the same and thenfed through a rotary winding head, which winds strands of insulatingmaterial upon the conductor from a plurality of cops secured thereto,while'the conductor is being'fed along from one end of the machine tothe other by suitable mechanism. The covered conductor is then fedrespectively to a binding compound applicator and a compressing andpolishing device.- These operations are needed in order to apply asingle layer of insulating material upon a conductor. In addition to thestructure noted above, some'form of driving mechanism and controlstherefor are required.

At the receiving end of the machine, a vertically directed standard 14is provided, upon the outer face of which is secured a bracket 17, Whichsupports a guide roller 18, and a wire straightening device 19. Belowthe bracket 17 andalso secured to the end face of the standard 14 is abase 20, upon which are mounted fixed and loose pulleys 22 and 21,respectively, which are supported upon a shaft 23, and which are adaptedto be driven by a power driven belt 24 from a power source, not shown. Achain sprocket wheel 25 is rotated by the shaft 23, being mountedthereon, and is rotatably connected by the chain 26 to a sprocket wheel27 secured upon a shaft 28. The shaft 28 is journaled on the base 20 at29 and 30, and adjacent the hearing 29 has a Hat face wheel 31 securedthereto. A strap brake 32 engages the periphery of the wheel 31 undertension of a spring 33, which acts upon an arm 34, secured to the strapbrake 32 and pivoted to a bracket 35 upon the base 20. An adjustingscrew 36 is provided which may be manipulated in a well known manner toadjust the tension on the spring 33. A belt shifting bar 37 extends fromthe bracket 35 to another bracket 38, and is provided with transverselyextending rods 39, which straddle the belt 24 and-engage the same toshift it from one pulley to the other upon movement of the bar 37.Sleeves 40 are provided to connect the rods 39 to the bar 37, one ofwhich is adapted to engage the arm 34 of the brake mechanism when thebar 37 is moved in the direction to shift the belt 24 to the fixed ortight pulley 22, and so release the brake by raising-it from engagementwith the periphery of the wheel 31, as shown by dotted lines in Fig. l.

A hollow stud shaft 41 is journaled in the upper end of the standard 14,and a cop or cheese supporting head 42 is keyed or otherwise secured tothis shaft. The head 42 is in the form of a disk andis provided with abelt groove 43 formed in the periphery thereof. Openings 44 are providedin the disk shaped head between which are radially disposed spokes orarms 45. A cop or cheese bearing pin 46 extends outwardly substantiallyat right angles from the face of the head and from each spoke or arm 45.A cop or cheese containing a length of roving 47 woiind upon a spool maybe slipped longitudinally with respect to the axis of the head upon eachof the pins 46, over a sleeve-like holder 49 which is rotatably mountedupon the pin 46, as shown in Fig. 9, and retained thereon-by a collar 48adapted to be secured to the pin 46 by a set screw. The spool or sleeve60 is adapted to tightly fit the sleeve-like holder 49. The holder 49 isprovided with a flange 50 at one end. A pin 51 extends outwardly towardthe end face of the head 42 from the flange 50, for apurpose to behereinafter described. A sheet metal rim or flange 74 extends from theperiphery of the head 42 axially over the cheeses of roving andsurrounds the same. A belt 75 engages the head 42 in the groove 43thereof and extends downwardlly about a pulley 77, secured to a shaft76.

he shaft 76 is connectedto the shaft 28 by any suitable type of coupling(not shown). The pulley 7 7 is provided with belt grooves of variousdiameters to permit the rotation of the head 42 at various speeds.

The machine is provided with a rear end standard 52 and longitudinallydirected members 53 and 54, 'which extend between the front standard 14and the rear standard 52. Upon the upper member 53 and hatemediate thestandards 14 and 52, a platform 55 is provided upon which is adjustablymounted a compound receiving tank 56.

Bearing pedestals 57 and 58 are provided upon the standard 52, in whichthe trunnions 0 a rotatable polishing device 59 are respectivelyjournaled. I

The belt shifting bar 37 extends from .the standard 14 to the standard.52. A shifting bar operating lever 61 is pivoted at one end thereof to alower supporting member 54-at 62, and extends outwardly and upwardlywithin reach of the operator of the machine. An arm 63 secured to thelever 61, extends upwardly therefrom and engages the shiftingbar 37 at64, whereby the same may be manipulated to shift the belt 24 from onepulley to theother. One end of a spring 65 is connected to the lever 61,and the other end thereof is connected to the standard 52. The spring 65operates, due to its tension, upon the lever 61 to urge-the bar 37 in adirection whereby the belt 24 will tend to be shifted or retained uponthe loose pulley 21. To prevent this action, except when it is desired,a catch 66 is secured to the bar 37 and engages a slidable pawl 67mounted on the standard 14, when the lever 61 is manipulated to move thebar 37 intoa position whereb the belt 24 is upon-the tight pulley 22. Te release of such engagement places the spring 65 in operation to againshift the belt over upon the loose pulley 21.

The pawl 67 is secured to a slide 68, which is slidably mounted upon abase 69, secured to the standard 14. The slide 68 is guided in itsmovements by the cooperation of the pawl 67, with an opening 70 in a lug71, upon the base 69, and by the cooperation of a stud 72 extendingupwardly from the slide 68 with an opening 1n a lug 73, also upon thebase 69.

A coil spring 78 constantly ur es the slide 68 downwardly against theln 1. A rotatable rod 79 is journaled in the ase 69 and extends theentire length of the machine. A cammin member 80 is secured to the rod79, and 1s disposed within an opening 81 in the slide 68. A flattenedsurface 82 upon the camming member 80, cooperates with a correspondingsurface 83 of the opening 81, whereby rotation of .the rod 79 will causethe camming member 80 to raise the slide 68 and thus draw the pawl 67out of engagement with the catch 66'. A handle 84 is secured to the rod79, whereby the same may be rotated manually by an operator of themachine. r

A bracket 85 is mounted upon the head 42 between each of the arms 45, soas to be disposed between the cheeses'of roving upon the spindles 46.Each bracket 85 supports a slida le pin 86 which is radially disposedwith respect to the axis of the head and which, in its lowermostosition, is adapted to move a lever 87 exten ing upwardly and secured atits lower end to the rod 79. A pin 88 extend ing from the lever 87 isdisposed in the path of the lower end of the pin 86, whereby it isengaged thereby to swing the'le'ver 87, thus rotating the camming member80 to release the catch 66 from the pawl 67. The pin 86 is retainedagainst outward radial movement due to the centrifugal force caused bythe rapid rotation of the head 42, by the engagement of an arm 89 of abell crank 90, which is pivoted at 91 to the bracket 85, with a collar92 secured to the pin 86. The other arm 93 of the bell crank has aroving engaging member 94, secured thereto, which, when the machine isin operation, lightly rides upon the strand of roving in such amannerthat the arm 89 is retained in position to hold the pin 86 radiallyinwardly and out of possible engagement with the pin 88 on the lever 87.An interruption in the strand of roving, due to breakage, or the like,will immediately release the pin 86 from the action of the arm 89, andthe lever 87 will be engaged to release the catch 66 from the pawl 67,whereby the belt shifting bar 37 will be moved by the spring 65 to shiftthe belt 24 on to the loose pulley 21, and causing the operation of thebrake 32 whereby the operation of the machine will stop.

It may be desired to operate the machine with one or more cheeses ofroving removed from the head 42. Under such circumstances, the pin 86normally controlled by the omitted cheeses will not be retained in anoperative position by the strand thereof, through the agency of thecrank arm 93, and the operation of the machine would not be permitted.Means to retain pins 86 under the above conarm 97 extends substantiallyradially with respect to the axis of the head, and is pro- I vi-ded withan end portion 98, which is adapted to moveto a position over the outerend of'the pin 86, when the crank 95 is rotated in one direction, and torelease the pin 86 from such engagement when the crank is moved intoanother position. The bell crank 95 is manually moved into pinengagingposition when the machine is set up. Another arm 99 of the bell crank95., extends toward the spindle 46 that holds the cheese of roving, withits end lying in the path of the pin 51, extending from the flange 50 ofthe holder 49, when the latter is upon the spindle 46. The arm 99,therefore, insures that the arm 97 will be moved to disengage theportion 98 thereof from the pin 86, when a cheese of roving is placedand rotated upon a spindle 46, reviously empty. The pin 51, during therst rotation of the corresponding cheese, engages the arm 99 to swingthe crank 95 into releasing position with respect to the pin 86.

A brake band 100 is swin ably mounted upon a stud 101, secured to theracket 85, and is urged in'to engagement with the periphery of anadjacent cheese of roving by aspring 102. The spring 102 is coiled aboutthe stud 101, with one end thereof secured thereto, the other end beingsecured to a member 103 towhich the brake band 100 is secured. The stud101 is adjustably journaled in an eX- tending portion 104 of the bracket85, being secured therein by means of a set screw 105. By loosening theset screw 105, the stud 101 may be rotated to adjust the tension of'thespring 102, so as to provide a suflicient amount of pressure of thebrake baud-100,

upon the cheese toprevent the same from.

spinning or from overrunning when the machine is in operation, therebykeeping the strand of roving taut.

The mechanism selected to illustrate the conductor feeding means abovementioned, comprises, in this instance, a Windlass section which may beoperably connected to the shaft 76 'by'co'i'i'pling the same to a shaft106, by means of a coupling member 107. Secured upon the shaft 106 is aworm 108 in mesh with a Worm wheel 109, secured upon a shaft 110, uponwhich is'a removable gear 111 of a set of change gears 111, and 112. Thegear 112 is removably secured to a shaft 113, upon which is secured apinion 114, which meshes with a gear 115, rotatablymounted upon a studshaft 116. The gear 115 is bolted to a Windlass drum 117 which isrotatably mounted upon the stud shaft 116. By a proper combination ofchange gears 111 and 112, the speed of the drum 117 may be adjusted tovary the speed at which the conductor 10 is fed or drawn through themachine preceding this Windlass. p

The conductor 10 received from any suit- \able source of supply, is fedthrough the straightening device 19, and is then passed through ahollowf shaft 41 and axially through the head 42. After passing throughe the head 42, the conductor-is fed through t compound applying tank 56,wherein suitable compound isvapplied to the insulationcovered'conductor. The conductor is then I passed through the wiping andpolishing dethe proper manipulation of the shifting bar" 37, by theoperating lever 61. The movement of the shifting bar 37 causes thesleeves 40 to engage the arm 34 ofthe brake 32 to move it into thedotted position shown in Fig. 1, where it is in inoperative position andunder tension of the spring 33, and released from engagement with thewheel 31. The arm 34 is retained in brake releasing position due to thebar 37' being retained in power applying position by means of thecooperation and engagement of the pawl 67 with the catch 66.

The strands of roving 12 are now started over the conductor, and therotation of the head about the same winds the roving thereon. TheWindlass being in operation, immediately starts to feed or draw theconductor longitudinally of the machine, and a layer of insulation-11 isapplied to the conductor 10 in long helical windings.

T Vhen the cops or cheeses 47 of roving are in place, and each isrotated upon the pin 46, the-pin 51 and the flange of the holder 49 willinsure that the arm 97 is swung into proper position to release the pin86, permitting it to move radially inward so that the lower endthereof'will clear the pin 88 in lever 87. The strand of roving 12, whenengaged by themember 94 and drawn taut, will rock the bell crank 90 andcause the arm 89 to draw the pin 86 inwardly into its inoperativeposition and retain it in such position against the centrifugal forceacting thereon to urge it outwardly into engagement with-pin 88.

Should the strand of roving 12 become slack and not have sufficienttautness to retain the pin 86 in inoperative position, the lever 87 willbe rocked by the engagement of pin 86 with pin 88, and the rod 79 willalso be rocked. The rocking of rod 79 operates the cam 80 to raise thepawl 67 and release the catch 66. Release of the catch 66,,permits thebar 37 to shift the belt 24 on to the loose pulley 21, and permits theapplication of the brake 32, whereby the operation ofthe machine isstopped. The same action of the parts will take place should the strandof roving 12 break, and also whenthe ends of the strand upon the cop orcheese 47 is reached.

The provision of the bell crank 95 with its pin engaging part 98 and arm99, prevents the operation of the machine when no cop or cheese 47 is inplace, unless the operator sets the part 98 in pin retainin position.This part, after being so set, will be automatically operated to permitthe free action of pin 86 as soon as the corresponding cheese 47 ismounted in place and rotated, at the most, one revolution.
